Electrophoretic deposition of flame retardant polymer–huntite coatings

Electrophoretic deposition method was used for deposition of composite coatings.Polymer-huntite coatings were deposited using huntite as a flame retardant additive.Alginic acid and hyaluronic acid were used as model polymers.Composite coatings showed flame retardant properties and corrosion protection.The coatings with large content of huntite can be obtained.

Electrophoretic deposition (EPD) method has been developed for the deposition of composite coatings, containing huntite as a flame retardant additive (FRA) in a polymer matrix. Alginate and hyaluronate were used as model anionic polymers for EPD. The adsorbed polymers allowed dispersion of plate-like huntite particles and imparted a charge for EPD. The deposition yield, microstructure, composition, and corrosion protective properties of the coatings were investigated. The results indicated that EPD is a promising technique for the fabrication of protective coatings, containing flame retardant additives.
